[0093] In addition, the sound acquisition unit 290 of the remote control device 200 may acquire voice.

[0094] The sound acquisition unit 290 may include at least one microphone and acquire voice through the microphone.

[0095] Next, Fig. 4 is described.

[0096] Fig. 4 is a view illustrating an example of utilizing a remote control device according to an embodiment of the present disclosure.

[0097] Fig. 4(a) illustrates that a pointer 205 corresponding to the remote control device 200 is displayed on the display unit 180.

[0098] A user may move or rotate the remote control device 200 vertically or horizontally. The pointer 205 displayed on the display unit 180 of the display device 100 corresponds to a movement of the remote control device 200. Since the corresponding pointer 205 is moved and displayed according to a movement on a 3D space as show in the drawing, the remote control device 200 may be referred to as a spatial remote control device.

[0099] Fig. 4(b) illustrates that if a user moves the remote control device 200, the pointer 205 displayed on the display unit 180 of the display device 100 is moved to the left according to the movement of the remote control device 200.

[0100] Information on a movement of the remote control device 200 detected through a sensor of the remote control device 200 is transmitted to the display device 100. The display device 100 may calculate the coordinates of the pointer 205 from the information on the movement of the remote control device 200. The display device 100 may display the pointer 205 to match the calculated coordinates.

[0101] Fig. 4(c) illustrates that while a specific button in the remote control device 200 is pressed, a user moves the remote control device 200 away from the display unit 180. Thus, a selected region in the display unit 180 corresponding to the pointer 205 may be zoomed in and displayed in an enlarged size.

[0102] On the other hand, if a user moves the remote control device 200 close to the display unit 180, a selection area in the display unit 180 corresponding to the pointer 205 may be zoomed out and displayed in a reduced size.

[0103] On the other hand, if the remote control device 200 is moved away from the display unit 180, a selection area may be zoomed out and if the remote control device 200 is moved closer to the display unit 180, a selection area may be zoomed in.

[0104] Additionally, if a specific button in the remote control device 200 is pressed, recognition of a vertical or horizontal movement may be excluded. In other words, if the remote control device 200 is moved away from or closer to the display unit 180, the up, down, left, or right movement cannot be recognized and only the back and forth movement may be recognized. While a specific button in the remote control device 200 is not pressed, only the pointer 205 is moved according to the up, down, left or right movement of the remote control device 200.

[0105] Moreover, the moving speed or moving direction of the pointer 205 may correspond to the moving speed or moving direction of the remote control device 200.

[0106] Furthermore, a pointer in this specification means an object displayed on the display unit 180 in response to an operation of the remote control device 200. Therefore, in addition to the arrow form displayed as the pointer 205 in the drawing, various forms of objects are possible. For example, the above concept includes a point, a cursor, a prompt, and a thick outline. Then, the pointer 205 may be displayed in correspondence to one point of a horizontal axis and a vertical axis on the display unit 180 and also may be displayed in correspondence to a plurality of points such as a line and a surface.

[0107] Meanwhile, the display device 100 is connected to an external speaker and transmits an audio signal to the external speaker, and the external speaker can output audio of an image that the user is watching based on the transmitted audio signal. The display device 100 can be connected to a plurality of external speakers, and each of the plurality of external speakers connected to the display device 100 can output audio of an image that the user is watching. At this time, the user may want to adjust the volume of only some of the plurality of external speakers according to the distance from the display device 100 or the like.

[0108] However, when a display device 100 and a plurality of external speakers are connected, there is a problem in that it is difficult to know which of the plurality of external speakers is adjusting the volume when there is a volume adjustment command.

[0109] Accordingly, a display device 100 according to one embodiment of the present disclosure is intended to enable the volume to be adjusted by selecting some of the plurality of external speakers when connected to a plurality of external speakers upon receiving a volume adjustment command.

[0110] First, an explanation is given with reference to Fig. 5.

[0111] Fig. 5 is a ladder diagram illustrating an operating method of a display device according to one embodiment of the present disclosure.

[0112] The display device 100 can be connected to at least one external speaker 400 (S10).

[0113] The wireless communication interface 173 can be connected to at least one external speaker 400. The wireless communication interface 173 can be connected to at least one external speaker 400 before an image is displayed on the display 180 or while an image is displayed on the display 180.

[0114] An audio signal of an image displayed on a display 180 in a display device 100 can be transmitted to an external speaker 400 (S20).

[0115] The controller 170 can transmit audio signals to each of the plurality of external speakers 400 when the display device 100 is connected to a plurality of external speakers 400.

[0116] An external speaker 400 can output audio based on a received audio signal (S30).

[0117] The external speaker 400 can output audio at a predetermined volume based on the received audio signal. The predetermined volume may be the volume last output by the external speaker 400. Alternatively, the predetermined volume may be the volume set as the initial volume of the external speaker 400.

[0118] Meanwhile, even if an external speaker 400 is connected, audio may be output from the speaker 185 included in the display device 100.

[0119] The remote control device 200 can transmit a volume adjustment command to the display device 100 (S40).

[0120] A user can press a volume adjustment button 235 provided on a remote control device 200 while an image is displayed on the display 180 and audio is output from an external speaker 400, and accordingly, the remote control device 200 can transmit a volume adjustment command to the display device 100.

[0121] The volume adjustment command may be a command to adjust the volume of at least some of the speaker 185 and the plurality of external speakers 400. The volume adjustment command may be a command to adjust the volume of at least some of the speaker 185 and the plurality of external speakers 400 to be larger or smaller.

[0122] Meanwhile, the user can press the volume adjustment button 235 provided on the remote control device 200 to cause the remote control device 200 to transmit a volume adjustment command to the display device 100, but this is only an example, and it is reasonable to assume that the method for transmitting the volume adjustment command is not limited thereto.

[0123] When the display device 100 receives a volume adjustment command, it can display a volume adjustment UI for adjusting the volume of the speaker 185 and the external speaker 400 (S50).

[0124] The controller 170 may display a volume adjustment UI when receiving a volume adjustment command. The volume adjustment UI may be a UI (User Interface) for adjusting the volume of the speaker 185 and the external speaker 400. The volume adjustment UI may visually display the current volume of the corresponding speaker 185 or the external speaker 400. For example, if the volume adjustment UI is in the form of a bar, the higher the height of the bar filled in may mean that the volume of the speaker 185 or the external speaker 400 corresponding to the volume adjustment UI is louder.

[0125] In addition, the volume adjustment UI is displayed and adjusted according to the UI adjustment command, and the volume of the speaker 185 or the external speaker 400 can be adjusted in response to the volume adjustment UI displayed and adjusted.

[0126] The remote control device 200 can transmit a command to select at least one of the displayed volume adjustment Uls (S60).

[0127] The user can select at least one of the volume adjustment Uls displayed on the remote control device 200 or by voice command. Accordingly, the remote control device 200 can transmit a command to select at least one of the volume adjustment Uls displayed on the display device 200.

[0128] The display device 100 can transmit a notification signal to an external speaker 400 corresponding to a volume adjustment UI selected by the user (S70).

[0129] The controller 170 can transmit a notification signal to an external speaker 400 corresponding to a volume adjustment UI selected by the user.

[0130] The notification signal may include any one of a notification sound signal, an LED signal, and a vibration signal.

[0131] An external speaker 400 that receives a notification signal can output a notification based on the notification signal (S80).

[0132] An external speaker that receives a notification sound signal can output a notification sound, an external speaker that receives an LED signal can output an LED lighting effect, and an external speaker that receives a vibration signal can output vibration.

[0133] Accordingly, the user can easily know which of the multiple external speakers 400 has its volume adjusted.

[0134] The remote control device 200 can transmit a UI adjustment command (S90).

[0135] The user can check which external speaker 400 outputs the notification, and if the external speaker 400 outputting the notification is the external speaker 400 whose volume is to be adjusted, the user can press the volume adjustment button 235 provided on the remote control device 200. Accordingly, the remote control device 200 can transmit a UI adjustment command to the display device 100.

[0136] When the controller 170 receives a UI adjustment command, the controller can adjust and display a volume adjustment UI in response to the UI adjustment command (S100).

[0137] For example, if the volume adjustment UI is in the form of a bar and the UI adjustment command is a command to increase the height of the bar by one level, the controller 170 can display the bar so that the filled height increases by one level. In addition, if the volume adjustment UI is in the form of a bar and the volume adjustment command is a command to decrease the volume by one level, the controller 170 can display the bar so that the filled height decreases by one level.

[0138] When the controller 170 receives a UI adjustment command, the controller can adjust and display a volume adjustment UI and transmit a volume adjusting signal corresponding to the UI adjustment command to an external speaker 400 (S110).

[0139] For example, the controller 170 may indicate that the height of the bar is increased by one level and transmit a volume adjustment signal so that a volume one level higher is output from the external speaker 400. Additionally, the controller 170 may indicate that the height of the bar is decreased by one level and transmit a volume adjustment signal so that a volume one level lower is output from the external speaker 400.

[0140] An external speaker 400 that receives a volume adjustment signal can output audio by adjusting the volume based on the volume adjustment signal (S120).

[0141] For example, when the external speaker 400 receives a volume adjustment signal that causes the volume to be output at one level lower, the external speaker can output audio at one level higher than the volume of the audio that was being output before receiving the volume adjustment signal. In addition, when the external speaker 400 receives a volume adjustment signal that causes the volume to be output at one level higher, the external speaker can output audio at one level lower than the volume of the audio that was being output before receiving the volume adjustment signal.

[0142] In summary, if a display device 100 according to one embodiment of the present disclosure has a plurality of external speakers 400 connected to the display device, the display device can display a plurality of volume adjustment Uls for adjusting the volume of each of the plurality of external speakers 400.

[0143] Next, referring to Fig. 6, an operation of displaying a volume adjustment UI for adjusting the volume of some of a plurality of external speakers by a display device 100 according to an embodiment of the present disclosure will be described.

[0144] Fig. 6 is an exemplary drawing for explaining a screen on which a display device displays a volume adjustment UI according to one embodiment of the present disclosure.

[0145] Referring to Fig. 6 (a) to (c), a first volume adjustment UI 411 for adjusting the volume of a first external speaker 410, a second volume adjustment UI 421 for adjusting the volume of a second external speaker 420, and a third volume adjustment UI 431 for adjusting the volume of a third external speaker 430 are displayed on the display 180. The first to third volume adjustment Uls 411, 421, 431 may be displayed on the screen being viewed. When three volume adjustment Uls are displayed in this manner, three external speakers may be connected to the display device 100. The number of volume adjustment Uls displayed on the display 180 may be the same as the number of external speakers 400 connected to the display device 100.

[0146] Meanwhile, the first volume adjustment UI 411, the second volume adjustment UI 421, and the third volume adjustment UI 431 may be displayed in a bar shape as illustrated in Fig. 6. However, this is only an example, and it is reasonable to assume that the shape of the volume adjustment UI is not limited thereto.

[0147] First, Fig. 6 (a) is a drawing illustrating a screen displayed on a display 180 when a controller 170 receives a volume adjustment command.

[0148] Referring to Fig. 6 (a), the first volume adjustment UI 411 may be displayed as being filled one level higher than the second volume adjustment UI 421. When the volume adjustment UI is displayed in a bar form, the higher the volume of audio output from the external speaker, the higher the volume of the volume adjustment UI corresponding to the external speaker may be displayed. In other words, the volume of audio output from the first external speaker 410 may be two levels higher than the volume of audio output from the second external speaker 420.

[0149] In addition, referring to Fig. 6 (a), the third volume adjustment UI 431 may be displayed as being filled one level lower than the second volume adjustment UI 421. When the volume adjustment UI is displayed in the form of a bar, the lower the volume of audio output from the external speaker, the lower the volume of the volume adjustment UI corresponding to the external speaker may be displayed. In other words, the volume of audio output from the third external speaker 430 may be three levels lower than the volume of audio output from the second external speaker 420.

[0150] Meanwhile, when the controller 170 receives a volume adjustment command, the controller can further display a guide 401 together with the volume adjustment UI. The guide 401 can be displayed around the volume adjustment UI to indicate which volume adjustment UI is selected among a plurality of volume adjustment Uls.

[0151] Referring to Fig. 6 (a), the guide 401 may be displayed as a square around the first volume adjustment UI 411. The guide 401 may indicate that the selected volume adjustment UI is the first volume adjustment UI 411. In other words, when the user issues a UI adjustment command while the guide 401 is displayed around the first volume adjustment UI 411, the first volume adjustment UI 411 will be controlled and displayed. Meanwhile, it is reasonable to assume that the guide 401 being displayed as a square is merely an example, and the shape of the guide 410 is not limited thereto.

[0152] Meanwhile, the remote control device 200 can transmit a command to move the position of the guide 401.

[0153] Fig. 6 (b) is a drawing illustrating a screen where a guide 401 is displayed around a second volume adjustment UI 421. As illustrated in Fig. 6 (a), when a guide 401 is displayed around a first volume adjustment UI 411, a user can press a right button among the direction buttons 213 of a remote control device 200. Accordingly, the remote control device 200 can transmit a command to move the position of the guide 401 to the right in the display device 100, and the controller 170 can cause the guide 410 to move to the right and be displayed around the second volume adjustment UI 421 based on the received command. Accordingly, the guide 401 can indicate that the selected volume adjustment UI is the second volume adjustment UI 421.

[0154] Next, Fig. 6 (c) is a drawing illustrating a screen displayed on the display 180 when the controller 170 receives a UI adjustment command to control the second volume adjustment UI 421.

[0155] Referring to Fig. 6 (c), the filled height of the second volume adjustment UI 421 is different from the filled height of the second volume adjustment UI 421 illustrated in Fig. 6 (a) to (b). In addition, the filled heights of the unselected first volume adjustment UI 411 and third volume adjustment UI 431 are the same as the filled heights of the first volume adjustment UI 411 and third volume adjustment UI 431 illustrated in Fig. 6 (a) to (b). In other words, some of the first to third volume adjustment Uls may be adjusted and displayed. The user may press the volume adjustment button 235 of the remote control device 200 while the guide 401 is displayed around the second volume adjustment UI 421, or press the confirmation button 238 and then press the volume adjustment button 235. Accordingly, the remote control device 200 can transmit a UI adjustment command to adjust the second volume adjustment UI 421 to the display device 100, and the controller 170 can adjust and display the second volume adjustment UI 421 based on the received UI adjustment command.

[0156] In addition, the filled height of the second volume adjustment UI 421 illustrated in Fig. 6 (c) is one level lower than the filled height of the first volume adjustment UI 411 illustrated in Fig. 6 (a) to (b). The controller 170 can adjust and display the volume adjustment UI in response to the received UI adjustment command, and transmit a volume adjustment signal corresponding to the UI adjustment command to the external speaker 400. In addition, the external speaker 400 can adjust and output the volume of audio based on the received volume adjustment signal. Since the second volume adjustment UI 421 of Fig. 6 (c) is filled one level lower than the second volume adjustment UI 421 of Fig. 6 (a) to (b), the volume of the second external speaker 420 can be one level lower than the volume of the second external speaker 420 output in Fig. 6 (a) to (b). In other words, since only the volume adjustment UI selected by the user is adjusted and displayed, the volume of only the external speaker corresponding to the selected volume adjustment UI can be adjusted and output.

[0157] In summary, if there are a plurality of external speakers 400 connected to the display device, the controller 170 can display a plurality of volume adjustment Uls for adjusting the volume of each of the a plurality of external speakers 400.

[0158] Accordingly, some of the plurality of external speakers 400 can be selected to control the volume, creating a sound environment optimized for the user.

[0159] Meanwhile, the user may want to adjust the volume of the speaker 185 included in the display device 100 rather than the external speaker 400 connected to the display device 100.

[0160] Accordingly, the display device 100 according to one embodiment of the present disclosure is intended to display a volume adjustment UI for adjusting the volume of audio output from the speaker 185 when receiving a volume adjustment command.

[0161] Fig. 7 is an exemplary drawing for explaining a screen in which a display device according to one embodiment of the present disclosure displays a volume adjustment UI of a speaker and an external speaker.

[0162] Referring to Fig. 7, the same screen as that illustrated in Fig. 6 may be displayed on the display 180. However, unlike that illustrated in Fig. 6, the display 180 may further display a fourth volume adjustment UI 186 for adjusting the volume of the speaker 185 included in the display device 100. The name of the display device 100 may be displayed at the top of the fourth volume adjustment UI 186 so that it can be recognized as a volume adjustment UI for adjusting the display device 100. Meanwhile, the fourth volume adjustment UI 186 may be displayed at a predetermined distance from the volume adjustment UI for adjusting the external speaker 400 so that it can be distinguished from the volume adjustment UI for adjusting the external speaker 400. Alternatively, the fourth volume adjustment UI may be displayed in a different color or in a different form from the volume adjustment UI.

[0163] The guide 401 may be displayed on the fourth volume adjustment UI 186 or moved to the periphery of the fourth volume adjustment UI 186. Accordingly, the user may adjust the volume of not only the external speaker 400 but also the speaker 185. For example, the user may press the volume adjustment button 235 of the remote control device 200 while the guide 401 is displayed on the fourth volume adjustment UI 186, and accordingly, the remote control device 200 may transmit a UI adjustment command for adjusting the fourth volume adjustment UI 186. Accordingly, the controller 170 may adjust and display the fourth volume adjustment UI 186 in response to the received UI adjustment command. In addition, the controller 170 may adjust the volume of the speaker 185 in response to the UI adjustment command.

[0164] Meanwhile, if at least one external speaker 400 of the display device 100 is connected, audio may not be output from the speaker 185. In this case, if there is a UI adjustment command for adjusting the fourth volume adjustment UI 186, the volume of all external speakers 400 connected to the display device 100 may be adjusted simultaneously.

[0165] In summary, the display device 100 according to one embodiment of the present disclosure can display a volume adjustment UI for adjusting the volume of the speaker 185 included in the display device 100 even when a volume adjustment command is given while an external speaker 400 is connected.

[0166] Accordingly, while allowing the volume of some of the plurality of external speakers 400 to be adjusted, it is also possible to adjust only the volume of the display device 100 or to adjust the volume of all connected external speakers 400 simultaneously, so that convenience in use can be increased.

[0167] Meanwhile, a user may want to adjust the volume of two or more external speakers among a plurality of external speakers 400 connected to the display device 100. Accordingly, the display device 100 according to one embodiment of the present disclosure allows the user to select the volume adjustment UI of each of two or more external speakers 400 simultaneously.

[0168] Fig. 8 is an exemplary drawing for explaining a screen displayed by a display device according to one embodiment of the present disclosure to simultaneously control two or more volume adjustment Uls.

[0169] Referring to Fig. 8 (a) to (c), a first volume adjustment UI 411 for adjusting the volume of a first external speaker 410, a second volume adjustment UI 421 for adjusting the volume of a second external speaker 420, and a third volume adjustment UI 431 for adjusting the volume of a third external speaker 430 may be displayed on the display 180. The first to third volume adjustment Uls 411, 421, 431 may be displayed on a screen being viewed. When three volume adjustment Uls are displayed in this manner, three external speakers may be connected to the display device 100. The number of volume adjustment Uls displayed on the display 180 may be the same as the number of external speakers 400 connected to the display device 100. Meanwhile, the first volume adjustment UI 411, the second volume adjustment UI 421, and the third volume adjustment UI 431 may be displayed in a bar shape as illustrated in Fig. 8. However, this is only an example, and it is reasonable to assume that the shape of the volume adjustment UI is not limited thereto.

[0170] Additionally, the display 180 may further display a first icon 412 for selecting a first volume adjustment UI 411, a second icon 422 for selecting a second volume adjustment UI 421, and a third icon 432 for selecting a third volume adjustment UI 431. The icons may include check boxes. Additionally, the number of icons may be the same as the number of volume adjustment Uls.

[0171] In addition, a guide 401 for indicating a selected volume adjustment UI may be further displayed on the display 180. The guide 401 may be displayed around the volume adjustment UI, but when an icon for selecting a volume adjustment UI is further displayed, it may be displayed around the icon as illustrated in Fig. 8.

[0172] First, Fig. 8 (a) is a drawing illustrating a screen displayed on a display 180 when a controller 170 receives a volume adjustment command.

[0173] Referring to Fig. 8 (a), the first icon 412 is checked. The checked icon may mean that the volume adjustment UI corresponding to the icon is selected. Accordingly, the checked first icon 412 may mean that the first volume adjustment UI 411 is selected.

[0174] Meanwhile, when the controller 170 receives a volume adjustment command, the controller can further display a guide 401 together with the volume adjustment UI. The guide 401 can be displayed around an icon to indicate which icon among a plurality of icons is checked or unchecked.

[0175] Referring to Fig. 8 (a), a guide 401 may be displayed as a square around a first icon 412. The guide 401 may indicate that the icon to be selected is the first icon 412. In other words, when the guide 401 is displayed around the first icon 412, the user may check or uncheck the first icon 412 by pressing the confirmation button 238 of the remote control device 200.

[0176] Fig. 8 (b) is a drawing illustrating a screen where the first icon 412 and the third icon 432 are checked. As illustrated in Fig. 8 (a), the user can press the right button among the direction buttons 213 twice while the first icon 432 is checked, and accordingly, the remote control device 200 can transmit a command to the display device 100 to move the guide to the right twice. The controller 170 can move the guide 401 to the vicinity of the third icon 432 based on the received command. In addition, the user can further check the third icon 432 by pressing the confirmation button 238 of the remote control device 200 while the guide 401 is displayed around the third icon 432. When the confirmation button 238 is pressed while the guide 401 is displayed around the checked icon, the icon is unchecked, and the selection of the volume adjustment UI is deselected. In addition, when a button displayed around an icon that is not checked in the guide 401 is pressed, the icon can be checked to select a volume adjustment UI. Since the first icon 412 and the third icon 432 are checked, the first volume adjustment UI 411 and the third volume adjustment UI 431 may be selected. The user can press the volume adjustment button 235 of the remote control device 200 while the first volume adjustment UI 411 and the third volume adjustment UI 431 are selected. Accordingly, the remote control device 200 can transmit a UI adjustment command to the display device 100 to adjust the first volume adjustment UI 411 and the third volume adjustment UI 431.

[0177] Next, Fig. 8 (c) is a drawing illustrating a screen displayed on the display 180 when the controller 170 receives a UI adjustment command made by the user by selecting the first volume adjustment UI 411 and the third volume adjustment UI 431. The first volume adjustment UI 411 and the third volume adjustment UI 431 of Fig. 8 (c) are filled one level lower than the first volume adjustment UI 411 and the third volume adjustment UI 431 of Fig. 8 (a) and (b). The controller 170 can simultaneously control and display the first volume adjustment UI 411 and the third volume adjustment UI 431 based on the received UI adjustment command. In addition, the controller 170 transmits a volume adjustment signal to adjust the volume of the first external speaker 410 and the third external speaker 430 to one level lower, and the first external speaker 410 and the third external speaker 430 can output audio by adjusting the volume of the audio to one level lower based on the received volume adjustment signal.

[0178] In summary, when the controller 170 receives a command adjustment command after two or more volume adjustment Uls are selected from among a plurality of volume adjustment Uls, it can simultaneously adjust the volume of each of a plurality of external speakers 400 corresponding to each of the plurality of volume adjustment Uls.

[0179] Accordingly, since there is no need to issue volume adjustment commands multiple times to adjust the volume of two or more external speakers 400, the loss of immersion in the image being viewed during the volume adjustment process can be minimized.

[0180] Meanwhile, the more external speakers 400 connected to the display device 100, the more volume adjustment Uls the controller 170 may display when receiving a volume adjustment command. Accordingly, it may be difficult for a user to find a volume adjustment UI corresponding to an external speaker for which the user wishes to control the volume.

[0181] Accordingly, a display device 100 according to one embodiment of the present disclosure is intended to display a plurality of volume adjustment Uls for adjusting the volume of each of a plurality of external speakers based on the priority of each of the plurality of external speakers.

[0182] For example, when the controller 170 displays a plurality of volume adjustment Uls from left to right, the volume adjustment UI for adjusting the external speaker with the highest priority may be displayed at the leftmost position. Alternatively, when the controller 170 displays the volume adjustment UIs from top to bottom, the volume adjustment UI for adjusting the external speaker with the highest priority may be displayed at the topmost position. This is merely an example, and it is reasonable that the method of displaying the volume adjustment UI is not limited thereto. However, in the present disclosure, it is assumed that the higher the priority of the external speaker, the more the corresponding volume adjustment UI is displayed on the left.

[0183] The controller 170 may obtain a priority for each of the plurality of external speakers 400 based on at least some of the following factors: a distance between each of the plurality of external speakers 400 and the display device 100, an order in which each of the plurality of external speakers 400 is connected to the display device 100, a number of times each of the plurality of external speakers 400 is connected to the display device 100, and a frequency with which the volume of each of the plurality of external speakers 400 is adjusted.

[0184] Next, a method for the controller 170 to obtain the priority of each of the plurality of external speakers 400 will be described in detail.

[0185] The controller 170 can obtain priorities for each of the plurality of external speakers 400 based on the volume of each of the plurality of external speakers 400. In relation to this, a detailed description will be given with reference to Fig. 9.

[0186] Fig. 9 is an exemplary drawing for explaining a screen in which a display device according to one embodiment of the present disclosure displays a volume adjustment UI based on the priority of each of a plurality of external speakers.

[0187] Figs. 9 (a) and (b) are drawings illustrating a display 180 screen that is displayed when the controller 170 receives a volume adjustment command.

[0188] The second volume adjustment UI 421 is filled one level higher than the third volume adjustment UI 431. This may mean that the volume of the second external speaker 420 is one level higher than the volume of the third external speaker 430. In addition, the first volume adjustment UI 411 is filled one level higher than the second volume adjustment UI 421. This may mean that the volume of the first external speaker 410 is one level higher than the volume of the second external speaker 420. In other words, the volume of the first external speaker 410 may be the loudest, and the volume of the third external speaker 430 may be the quietest.

[0189] Referring to Fig. 9 (a), it is assumed that the external speaker with a higher priority is displayed on the left, so it can be seen that the first volume adjustment UI 411 for adjusting the volume of the first external speaker 410 is displayed in the first priority, the second volume adjustment UI 421 for adjusting the volume of the second external speaker 420, and the volume adjustment UI 431 for adjusting the volume of the third external speaker 430 are displayed in the third priority.

[0190] The controller 170 can obtain that an external speaker with a larger volume has a higher priority. In addition, the controller 170 can obtain that an external speaker with a larger volume has a higher priority when the user's volume adjustment command is a command to decrease the volume.

[0191] Meanwhile, referring to Fig. 9 (b), it is assumed that the external speaker with a higher priority is displayed on the left, so it can be seen that the third volume adjustment UI 431 for adjusting the volume of the third external speaker 430 is displayed in the first priority, the second volume adjustment UI 421 for adjusting the volume of the second external speaker 420, and the volume adjustment UI 411 for adjusting the volume of the first external speaker 410 are displayed in the third priority.

[0192] The controller 170 can obtain that an external speaker with a lower volume has a higher priority. In addition, the controller 170 can obtain that an external speaker with a lower volume has a higher priority when the user's volume adjustment command is a command to adjust the volume loudly.

[0193] In Fig. 9, the volume adjustment UI for adjusting the volume of external speakers 400 is described as being arranged in order of high or low volume, but this is only an example, and the order may be changed based on any one of the priorities described above.

[0194] According to one embodiment, the controller 170 may further display a menu 402 for selecting the order in which the volume adjustment Uls are arranged. The menu 402 for selecting the order in which the volume adjustment Uls are arranged may include items such as distance, connection order, number of connections, adjustment frequency, and volume size. The user may select each item by pressing the direction button 213 or the confirmation button 238 of the remote control device 200, and accordingly, the remote control device 200 may transmit a command to select each item to the display device 100. The controller 170 may receive the command to select each item, and may obtain the priority of each of the plurality of external speakers 400 based on the received priority. Then, the controller 170 may sort and display a volume adjustment UI for adjusting the volume of each of the plurality of external speakers 400 based on the obtained priority.

[0195] Next, the method by which the controller 170 obtains priority will be specifically described.

[0196] The controller 170 can obtain priorities for each of the plurality of external speakers 400 based on the distance from each of the plurality of external speakers 400.

[0197] For example, when the controller 170 receives a command to select a distance item, the controller 170 can obtain the distance from each of the plurality of external speakers 400 based on the intensity of the signal received from each of the plurality of external speakers 400. The farther the external speaker 400 is from the display device 100, the weaker the intensity of the signal that the controller 170 receives from the external speaker 400. Accordingly, the controller 170 can obtain that the external speaker 400 is farther away as the intensity of the signal received from the external speaker 400 is weaker. However, this is merely an example, and it is reasonable to assume that the method by which the controller 170 obtains the distance from each of the plurality of external speakers is not limited thereto.

[0198] The controller 170 can be obtained by giving a higher priority to an external speaker 400 that is farther away from the display device 100. Accordingly, the volume output from a location farther away from the display 180 can be adjusted to adjust the audio spatial sense.

[0199] Conversely, the controller 170 can obtain that the external speaker 400 closer to the display device 100 has a higher priority. Accordingly, the volume output from a location closer to the display 180 on which the image screen is displayed can be adjusted with priority.

[0200] The controller 170 can obtain priorities for each of the plurality of external speakers 400 based on the order in which each of the plurality of external speakers 400 is connected to the display device 100.

[0201] For example, when the controller 170 receives a command to select a connection order item, each of the plurality of external speakers 400 can obtain a priority based on the order in which they are connected to the display device 100.

[0202] The most recently connected external speaker 400 may be an external speaker that has not yet been adjusted to an appropriate volume for the user. Accordingly, the controller 170 may obtain that the external speaker 400 most recently connected to the display device 100 has the highest priority.

[0203] Meanwhile, the external speaker 400 connected first may be the external speaker 300 used as the main by the user. Accordingly, the controller 170 may obtain that the external speaker 400 connected first has the highest priority.

[0204] The controller 170 can obtain a priority for each of the plurality of external speakers 400 based on the number of times each of the plurality of external speakers 400 is connected to the display device 100.

[0205] For example, when the controller 170 receives a command to select a connection order item, each of the plurality of external speakers 400 can obtain a priority based on the number of times each is connected to the display device 100.

[0206] The external speaker 400 connected to the display device 100 the most may be the external speaker 400 that the user uses as the main speaker. Accordingly, the controller 170 may obtain a higher priority for the external speaker 400 that is connected to the display device 100 the most.

[0207] Meanwhile, the external speaker 400 connected to the display device 100 the least number of times may be an external speaker 400 that is not adjusted to a volume suitable for the user. Accordingly, the controller 170 can obtain a higher priority for an external speaker 400 that is connected to the display device 100 less frequently.

[0208] The controller 170 can obtain a priority based on the frequency with which the volume of each of the plurality of external speakers 400 is adjusted for each of the plurality of external speakers 400. For example, when the controller 170 receives a command to select an adjustment frequency item, the controller 170 can obtain a priority based on the number of times the volume of each of the plurality of external speakers 400 is adjusted for a preset period of time.

[0209] The more times an external speaker 400 is adjusted during a preset time period, the more frequently the user adjusts the volume of the external speaker 400. Accordingly, the controller 170 can obtain that an external speaker 400 that is adjusted during a preset time period has a higher priority.

[0210] Meanwhile, the external speaker 400 that has been adjusted fewer times during a preset time may be an external speaker 400 that has not been adjusted to a volume suitable for the user. Accordingly, the controller 170 may obtain that the external speaker 400 that has been adjusted fewer times during a preset time has a higher priority.

[0211] However, it is reasonable to assume that the method in which the above-described controller 170 obtains the priority of a plurality of external speakers 400 is only an example and is not limited thereto.

[0212] In summary, a display device 100 according to one embodiment of the present disclosure can obtain the priority of each of a plurality of external speakers 400 and display a volume adjustment UI based on the priority.

[0213] Accordingly, the convenience of use can be increased by first displaying the volume adjustment UI of the external speaker 400 whose volume the user is most likely to control among the plurality of external speakers 400.

[0214] Meanwhile, the display device 100 according to one embodiment of the present disclosure may also adjust the volume of some of the plurality of external speakers 400 by entering a menu for changing the setting status of the external speakers when a plurality of external speakers 400 are connected.

[0215] In relation to this, it is explained with reference to Fig. 10.

[0216] Fig. 10 is an exemplary drawing for explaining a screen in which a display device according to one embodiment of the present disclosure displays a menu for changing the usage status setting of a display device or an external speaker.

[0217] When the controller 170 receives a user input for entering the setting menu, it can display a setting menu (m) for changing the usage status of the display device 100 or external speaker 400 as illustrated in Fig. 10 (a). The setting menu m can include screen, sound, general, and customer support items.

[0218] When the controller 170 receives a user input for selecting an audio item from the setting menu m, it may further display a first menu including items corresponding to each of a plurality of external speakers 400 connected to the display device 100, as illustrated in Fig. 10 (b). For example, the first menu may include items corresponding to the first external speaker 310 and the second external speaker 320.

[0219] In addition, when the controller 170 receives a user input for selecting one of the items corresponding to each of the plurality of external speakers 400, the controller 170 may further display a second menu m2 for changing the usage status of the external speaker 400 corresponding to the selected item, as illustrated in Fig. 10 (c). For example, when the controller 170 receives a user input for selecting an item corresponding to the first external speaker 310, the controller 170 may further display a second menu m2 for changing the usage status of the first external speaker 310. The second menu m2 may include items for volume adjustment, disconnection, and equipment deletion.

[0220] When the controller 170 receives a user input for selecting a volume control item, the controller 170 may further display a volume adjustment UI m3 for adjusting the volume of the external speaker 400 as illustrated in (d) of Fig. 10. For example, when the controller 170 receives a user input for selecting a volume control item included in a second menu m2 displayed by receiving a user input for selecting an item corresponding to the first external speaker 310, the controller 170 may further display a volume adjustment UI m3 for adjusting the volume of the first external speaker 310.

[0221] When a volume adjustment UI is displayed, the user can adjust the volume adjustment UI by issuing a UI adjustment command. For example, when a volume adjustment UI m3 for adjusting the volume of the first external speaker 310 is displayed, the user can control the volume adjustment UI by issuing a UI adjustment command.

[0222] When receiving a UI adjustment command, the controller 170 may adjust and display a volume adjustment UI in response to the volume adjustment command, and transmit a volume adjustment signal to the external speaker 400 so that the volume of audio output from the external speaker 400 is adjusted. For example, when receiving a UI adjustment command for adjusting a volume adjustment UI for adjusting the volume of the first external speaker 310, the controller 170 may adjust and display the volume adjustment UI, and transmit a volume adjustment signal to the first external speaker 310. Accordingly, the first external speaker 310 may adjust and output the volume of audio based on the received volume adjustment signal.

[0223] Meanwhile, the volume adjustment UI may be displayed when receiving a user input for selecting a volume control item from the second menu as described above, but this is merely an example and is not limited thereto. In other words, the volume adjustment UI may be displayed by being included in each item corresponding to each of the plurality of external speakers 400 in the first menu. In addition, the volume adjustment UI may be displayed by being included in the volume adjustment item in the second menu. Accordingly, the user has the advantage of being able to adjust the volume of any one of the plurality of external speakers 400 without entering a submenu.

[0224] In summary, the display device 100 according to one embodiment of the present disclosure can enter a menu for setting the usage status of the external speakers 400 and adjust the volume of some of the connected external speakers 400.

[0225] Accordingly, the user can change different usage states of the display device 100 or external speakers 400 and adjust the volume of some of the external speakers 400, thereby increasing convenience of use.

[0226] A display device 100 according to one embodiment of the present disclosure can create an optimized sound environment for a user by adjusting the volume of some of a plurality of external speakers 400.

[0227] In addition, the display device 100 according to one embodiment of the present disclosure can easily adjust the volume of some of a plurality of speakers and minimize the decrease in immersion in the image being viewed during the volume adjustment process.

[0228] According to one embodiment of the present disclosure, the above-described method can be implemented as a processor-readable code on a medium in which a program is recorded. Examples of the processor-readable medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like.

[0229] The display device described above is not limited to the configuration and method of the embodiments described above, and the embodiments may be configured by selectively combining all or part of the embodiments so that various modifications can be made.
